The equation Fe + 5Hg(NO3)2 -> 2Fe(NO3)3 + 5Hg

  1. Detailed information about the equation Fe + 5Hg(NO3)2 -> 2Fe(NO3)3 + 5Hg:

This equation describes a chemical reaction that takes place between iron (Fe) and mercury(II) nitrate (Hg(NO3)2), resulting in the formation of iron(III) nitrate (Fe(NO3)3) and mercury (Hg).

  1. Reaction conditions:

This reaction occurs at room temperature. However, increasing the temperature can help accelerate the reaction rate.

  1. Reaction process:

When iron (Fe) is in contact with mercury(II) nitrate (Hg(NO3)2), it engages in a chemical reaction with it, resulting in the production of iron(III) nitrate (Fe(NO3)3) and mercury (Hg). In this process, iron loses electrons to become iron ion (Fe3+), while mercury ion (Hg2+) accepts electrons to revert to its atomic form.

  1. Observed phenomena:

During the reaction, we can observe a change in the color of the solution. The solution of mercury(II) nitrate is transparent white, but after the reaction, it turns yellow due to the formation of iron(III) nitrate. Mercury appears as silver particles in the solution.
